IMPROVED COAL-OIL BURNER.

Specification forming part of Letters Patent No. 38,070, dated March 31, 1863.

To all whom it may concern.-

Be it known that I, EMIL TRITIIN, of Philadelphia, Pennsylvania, have invented an Improvem ent in Burners for Coal-Oil Lamps and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in the lamp-burner for which Letters Patent were granted to me on the 19th day of August, 1862; and my improvement consists in isolating or partially isolating the screw which forms the lower portion of the burner from the upper portion and from the wick-tube by connectin g the said screw to the dome or deflector through the medium of certain projections and a plate with projections, substantially as described hereinafter.

The object of my invention is to prevent more effectually than by the plan described in the said patent the conduction of heat from the burner to the reservoir or fountain of the lamp.

In order to enable others skilled in the art to make my invention, I will now proceed to describe the manner of constructing the same.

On reference to the accompanying drawings, which form a part of this specification, Figure 1 is a vertical section of my improved burner for coal-oil lamps; Fig. 2, a transverse vertical section on the line 1 2, Fig. 1; and Fig. 3, an inverted plan view.

Similar letters refer to similar parts throughout the several views.

A is the cone or bell-shaped cap or (as it is sometimes termed) deflector of the burner, having at the sides perforations for the admission of air, and at the top the usual oblong slot, a directly above the ordinary flat wicktube B.

D is a circular plate or disk situated at or near the lower end of the deflector A, the plate being less in diameter than the lower portion of this deflector, to which it is connected through the medium of any convenient number of small arms or projections 01, forming part of the plate, and being secured to the deflector by soldering or otherwise.

E represents the lower portion or (as it is sometimes termed) the screw of the burner which is attached to the fountain or reservoir. From the upper portion of this screw project three or any other suitable number of arms or projections e, the ends of which are secured by soldering or otherwise to the under side of the circular plate or disk D, to which the wick-tube B is secured, the wick itself being elevated or lowered at pleasure by means of the usual cog-wheels G on a spindle, H, the teeth of the said wheels projecting through slots in the said wick-tube. It should be observed that this tube is not in contact with the screw of the reservoir, but that the lower end of the tube, being a short distance above the bottom of the screw, is isolated from the same, the only connection of the tube with the burner being through the medium of the plate D and its arms 01 d.

It is well known that the main objection to coal-oil-lam p burners of the ordinary construction is the medium which they present for conducting the heat of the flame to the fountain or reservoir, thereby causing an undue evaporation or volitilization of the oil, and cansing a too copious supply of vapor to ascend to the flame. In my patent of August 19, 1862, this objection was in a measure obviated by dividing the wick-tube into two parts, one part (which was free from contact with the other) being secured to a plate analogous to that marked D in the accompanying drawin gs, and the other part being secured to the screw E. This plan accomplished the result desired, but not so completely as that described in my present invention, which I consider a marked improvement on that set forth in my aforesaid patent.

It will be observed that the wick-tube B, although in one piece, does not present a direct medium for conducting the heat from the burner, or rather the deflector A of the burner to the reservoir, inasmuch as the lower end of the tube is free from contact with the screw E, and as this screw is connected through the medium of light arms to the plate D, and the latter through the medium of similar arms to the deflector A, all these arms being exposed to the direct action of the cold air, the screw E of the reservoir is sufficiently isolated from the burner to be free from the inordinate and objectionable heat towhich the screw of orditions 01 d on the said plate, substantially as nary coal-oil burners arenecessarily subjected. set forth.

I claim as my invention and as an improve- In testimony whereof I hat e signed my ment on my aforesaid patent of August 19, name to this specification in the presence of 1862- two subscribing Witnesses.
